SUSPENSION MEANS FOR POURING DEVICES.

Application led December 22, 1917.

To all @07mm t may concern.'

Be it known that I, FREDERICK G. ySTEW- ART, a citizen of the United States, residing at Stockton, in the county of San Joaquin and State of California, have invented a new and useful Improvement in Suspension Means for Pouring'. Devices, of which the following is a specication.

This invention relates to suspension means for pouring devices used in foundries and the like to pour molten metal into molds of various sorts, and hasV for its object to provide a device of this character, simple in constructiom, cheap to manufacture and readily operable and adjustable to any desired position by one person.

Pouring devices of this sort are ordinarily supported from overhead trolleys or like movable carriers which are adapted to travel on tracks, bridges, or the like, so that the molten metal may readily be transported from the furnaces to the lvarious molds. It is highly desirable that the curing device be readily adjustable to di 'erent altitudes for pouring a multiplicity of molds of different sizes, and to prevent any spilling and subsequent wastage of metal quite exact vertical adjustment of the pouring ladle is required.

The device as shown and described is especially adapted to small. and medium sized work and because of its compactness and simplicity, and particularly because of the ease of adjustment and operation thereof, its use lowers the cost of pouring, mate- I rially increases the output, prevents wastage of metal and diminishes the labor necessarily done by the operator of the pouring device.

In the accompanying drawings:

Figure 1 is a sectional elevation of a pouring device vand the suspension means therefor embodying the invention, attached to its overhead support, taken on line 1-1,Fig. 2.

Fig. 2 is an elevation of the suspension means and pouring device taken at right angles to Fig. 1. j

The device which forms the subject of the present invention is provided with two distinct adjusting mechanisms which are utilized respectively for fixing the approximate height of the pouring ladle, and for .Specification of Letters Patent.

highest degree of eliiciency. The adjusting devices shown in the drawings are the preferred means employed for such purposes, but it is 'not intended to limit the invention to thel forms shown, and other adjusting mechanism by which the same results may be accomplished can be used in place thereof if desired. In the preferred construction shown, the overhead support for the device is shown as comprising a trolley or carrier 3 which is adapted to travelon the track 4. These partsV form no part of the present invention, and the suspension device can be used with any other suitable form of overhead support.

.Y 5 is a suspension rod which is provided with a hooked end 6 adapted to engage with the trolley 3. The lower portion of the rod is' preferably forked as indicated at 7, and is provided, `preferably at the lower extremity of the rod, with a socket 8 having a screwthreaded opening 9 therein. If desired any other suitable construction of rod can be used instead of the form shown. 10 is a supporting bar o r member which is also preferably forked, as indicated at 11. 12 is a socket formed preferably at the upper portion of this member and having the screw-threaded opening 13 formed therein. 1

As shown, the preferred adjusting means lby which approximate adjustment of the ladle is obtained, consists of a turn-buckle 14 which is located between the rod 5 and the member 10, such turn-buckle being provided with an operating handle 15, and havinO' its upper and lower extremities 16 and l( provided with a right and left hand .thread respectively and adapted to enter reing one extremity thereof bent upwardly as indicated at 22. Any other suitable supplementary adjusting means may be substituted for the ratchet arrangement shown, if desired; nor is it intended to limit the vinvention to mounting said supplementary adjusting means below the approximate adjusting means and the member 10.'vv

In the preferred construction shown, the end of the ratchet lever 20 is provided with lugs 23 by which a link 24 is supported in such a way as to allow free movement thereof in a vertical plane.

26 represents the usual form of pouring ladle, provided with trunnions 27. 28 is the ladle yoke, the bent ends 29 of which are adapted to hook under the ladle trunnions 27 30 is an opening formed at ,the upper portion of the yoke. The link 24: is provided lwith a shaft or boltr 31 at its lower extremity, Vhaving a head 32, and this shaft passes through the opening 30 of the ladle yoke, thus serving to form a swivel connection between the yoke and the suspension device. 33-is a handle of usual form removably attached to the ladle for tilting ythe same. l

The device is adapted for use with any suitable form of pouring ladle and support therefor and if desired such form maybe substituted for the ladle and yoke shown.

In operating the device, the approximate height to which it is required to raise the ladle is first fixed by manipulation of the turn-buckle, or the adjusting means which may be used in place thereof, and the exact height required is then secured by adjustment of the ratchet handle or other supplementary adjusting means. In this way perfect adjustment of the ladle can be secured with a minimum amount of effort and much better results are obtainable than when only a single adjusting mechanism is utilized. By swinging the ratchet handle shown in a horizontal plane, either alone or in connection with the handle of the turn-buckle, a corresponding movement is imparted to the ladle, and the swivel joint connection formed between the suspension device and the ladle yoke greatly facilitates the ease with which the ladle can be used in a number of varying positions.
